Accurately boresighting your weapon with a laser is crucial for effective shooting, especially at longer ranges. A properly boresighted weapon ensures your point of aim matches your point of impact, maximizing accuracy and minimizing wasted ammunition. This guide provides a step-by-step process for boresighting, covering essential safety precautions and troubleshooting common issues.
What is Boresighting?
Boresighting aligns the weapon's sights (iron sights or optics) with the barrel's bore. This means the laser, mounted on the weapon, should point exactly where the bullet will travel when fired. An improperly boresighted weapon will result in significant misses, even at close range. Using a laser boresighting tool simplifies this process considerably, especially for those unfamiliar with traditional boresighting methods.
Safety First: Essential Precautions Before Boresighting
Before you even begin, prioritize safety:
- Treat every firearm as if it were loaded: This is the cardinal rule of firearm safety. Always double-check that your weapon is unloaded before handling it.
- Wear eye protection: Laser light, even from boresighting lasers, can damage your eyes. Use appropriate eye protection throughout the process.
- Choose a safe location: Select a location free from obstructions and where stray laser beams won't pose a risk to others. Consider using a backstop to catch any stray shots, should the laser not be perfectly aligned and accidental discharge occurs.
- Understand your weapon: Familiarize yourself with your firearm's operation and safety mechanisms before attempting boresighting.
Equipment Needed for Boresighting with a Laser
- Laser Boresight: This is the key tool, specifically designed to fit your weapon's caliber.
- Weapon to be Boresighted: Ensure it's properly cleaned and maintained.
- Target: A suitable target at a safe distance.
- Eye Protection: Safety glasses are essential.
- Appropriate Tools: Depending on the boresight and weapon, you may need a screwdriver or other tools for attachment and adjustment.
- Measuring Tape (Optional): For more precise measurements and adjustments, particularly at longer distances.
Step-by-Step Guide to Boresighting with a Laser
-
Prepare your Weapon: Ensure your weapon is unloaded and safe. Remove the magazine and visually and physically check the chamber to confirm it's empty.
-
Install the Laser Boresight: Carefully insert the laser boresight into the weapon's barrel according to the manufacturer's instructions. Ensure a secure fit.
-
Choose a Safe Distance and Setup: Set up your target at a reasonable distance (25 yards or more is recommended for accuracy). Ensure a safe backstop is in place.
-
Aim and Adjust: Aim the weapon at the center of the target. Most laser boresights offer adjustment screws (usually windage and elevation) to fine-tune the laser's point of impact.
-
Make Adjustments: Adjust the screws until the laser point is centered on the target. Small adjustments are usually all that are required.
-
Verify Accuracy: Once you've made your adjustments, re-check the laser's point of impact on the target. If necessary, make small further adjustments until you achieve the desired accuracy.
Troubleshooting Common Boresighting Issues
- Laser is significantly off target: This could indicate an issue with the laser boresight itself, improper installation, or a problem with the weapon's alignment. Re-check all steps carefully.
- Laser is too dim: Ensure your boresight has fresh batteries.
- Difficulty adjusting: Make sure you are correctly adjusting the adjustment screws, according to the manufacturer’s instructions.
Conclusion
Boresighting your weapon with a laser is a relatively simple process that can significantly improve your shooting accuracy. By following these steps and adhering to safety precautions, you can ensure your weapon is properly aligned, leading to improved performance on the range or in the field. Remember, practice makes perfect! Consistent practice after boresighting will help you further refine your shooting skills.
